Rear Window and Outside Mirror
Defogger
Your vehicle has a rear window and outside mirror
defogger. This feature will only work when the ignition is
turned to ON.
The rear window defogger uses a warming grid to
remove fog or frost from the rear window. Before using
this feature, clear as much snow from the rear
window as possible.
window and outside mirror defogger on or off. The
button is located below the audio system. An indicator
light in the button will come on to let your know that the
feature is activated.
The rear window and outside mirror defogger will turn
off about 10 minutes after the button is pressed.
The defogger can also be turned off by pressing the
button again or by turning off the engine.
Notice:Don’t use anything sharp on the inside of
the rear window. If you do, you could cut or damage
the warming grid, and the repairs wouldn’t be
covered by your warranty. Do not attach a temporary
vehicle license, tape, a decal or anything similar
to the defogger grid.
Front Heated Windshield
Your vehicle may have a heated front windshield which
can be used to defrost it. This feature will only work
when the ignition is turned to ON.
There is a heated element along the bottom of the
windshield used to heat the windshield.

If you drive regularly in steep country, or if you are
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
•Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system,
and transaxle. These parts can work hard on
mountain roads.
•Know how to go down hills. The most important
thing to know is this: let your engine do some of
the slowing down. Shift to a lower gear when you go
down a steep or long hill.
{CAUTION:
If you do not shift down, your brakes could get
so hot that they would not work well. You
would then have poor braking or even none
going down a hill. You could crash. Shift down
to let your engine assist your brakes on a
steep downhill slope.
{CAUTION:
Coasting downhill in NEUTRAL (N) or with the
ignition off is dangerous. Your brakes will have
to do all the work of slowing down. They could
get so hot that they would not work well. You
would then have poor braking or even none
going down a hill. You could crash. Always
have your engine running and your vehicle in
gear when you go downhill.
•Know how to go uphill. Drive in the highest gear
possible.
•Stay in your own lane when driving on two-lane
roads in hills or mountains. Do not swing wide
or cut across the center of the road. Drive at speeds
that let you stay in your own lane.
•As you go over the top of a hill, be alert. There
could be something in your lane, like a stalled car or
an accident.
•You may see highway signs on mountains that
warn of special problems. Examples are long
grades, passing or no-passing zones, a falling rocks
area, or winding roads. Be alert to these and take
appropriate action.

need to check your engine
oil level right away.
For more information, seeOil Pressure Light on
page 3-44.
You should check your engine oil level regularly; this is
an added reminder.
5-13

Automatic Transaxle Fluid
It is not necessary to check the transaxle fluid level. If a
leak occurs, take the vehicle to the dealership service
department and have it repaired as soon as possible.
Have your dealer or service center change both the fluid
and filter every 50,000 miles (83 000 km) if the vehicle
is mainly driven under one or more of these conditions:
•In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
•In hilly or mountainous terrain.
•Uses such as found in taxi, police or delivery
service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
Notice:Use of automatic transaxle uid labeled
other than ESSO LT71141 or TOTAL ATF H50235
may damage your vehicle, and the damages may not
be covered by your warranty. Always use
ESSO LT71141 or TOTAL ATF H50235 labeled
automatic transaxle uid.
Engine Coolant
The following explains your cooling system and how to
add coolant when it is low. If you have a problem
with engine overheating, seeEngine Overheating on
page 5-22.
A 50/50 mixture of clean, drinkable water and proper
coolant will:
•Give freezing protection down to−22°F (−30°C).
•Give boiling protection up to 268°F (131°C).
•Protect against rust and corrosion.
•Help keep the proper engine temperature.
•Let the warning lights and gages work as they
should.
5-19

What to Use
Use a 50/50 mixture ofclean, drinkable waterand
coolant that meets GM specification 1825M, which will
not damage aluminum parts. You can also use a
recycled coolant conforming to GM specification 1825M
with a complete coolant flush and refill. If you use
this coolant mixture, you do not need to add
anything else.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will. Your
vehicle’s coolant warning system is set for the
proper coolant mixture. With plain water or the
wrong mixture, your engine could get too hot
but you would not get the overheat warning.
Your engine could catch re and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and the proper coolant.Notice:If you use an improper coolant mixture,
your engine could overheat and be badly damaged.
The repair cost would not be covered by your
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core and
other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
Notice:If you use the proper coolant, you do not
have to add extra inhibitors or additives which claim
to improve the system. These can be harmful.
5-20

Checking Coolant
The engine coolant surge
tank is located in the
engine compartment on
the passenger’s side of the
vehicle. SeeEngine
Compartment Overview on
page 5-12for more
information on location.
{CAUTION:
Turning the surge tank pressure cap when the
engine and radiator are hot can allow steam
and scalding liquids to blow out and burn you
badly. Never turn the surge tank pressure
cap — even a little — when the engine and
radiator are hot.The vehicle must be on a level surface. When your
engine is cold, the coolant level should be between the
MAX (A) and MIN (B) marks on the coolant surge
tank. The level rises at engine operation temperature
and drops again when the engine cools down.
Adding Coolant
If the level falls below the MIN (B) mark, add the proper
coolant mixtureat the surge tank,but only when the
engine is cool. If the surge tank is empty, a special fill
procedure is necessary. SeeCooling System on
page 5-24for instructions on “How to Add Coolant to
the Coolant Surge Tank.”
{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.
When replacing the pressure cap, make sure it is
hand-tight.
